TALKING-PICTURE APPARATUS Application med June 13,

My invention relates broadly to talking picture apparatus and moreparticularl to a construction of mounting for the llght source used in atalking picture projectlng system.

One of theobjects of my invention is to provide a constructionof-housi-ng for a light source in a talking picture projecting system.

Another object of my invention is to provide a housing for the lampsource of a talking picture projecting system which lamp housing may bemounted immediately adjacent the motion picture projecting machine forcontrolling the talking picture light source from a position immediatelyadjacent the controls of the motion picture projecting apparatus.

Still another object of my invention is so to provide a construction oflamp housing and control equipment for the light source of a talkingpicture system wherein the control equipment for mounting upon aswinging panel member which forms part of the housing for the lightsource for permitting access to be had to the light source foradjustment without interference with the controls adjacent the lightsource.

Other and further objects of my invention will be understood from thespecification hereinafter following by reference to the accompanyingdrawings, in which:

Figure 1 isa front elevation of the control panel on the lamp housing ofmy invention; Fig. 2 is a cross-sectional view through the lamp housingshowing the interior of the housing; Fig. 3 is a verticalcross-sectional view through the housing on line 33 of 0 Fig. 2illustrating the assembly of the controls within the housing and Fig. 4illustrates the position of the control panel with respect to the lamphousing when the lamp housing is opened for adjustment of the lightsource.

In talking picture systems, it is necessary to accurately control theintensity of the light source and adjustment of the position of thelight source may be required from time to time. My invention is directedto a housing for the light source, wherein the 1927. Serial No.198,848.-

controls are mounted on a panel immediately adjacent the light sourceand the panel provides one wall of the housing which encloses the lightsource. The panel is right angular in cross-section and may be swung toa position remote from the light source opening the housing to permitaccess to be had to the adjustable mounting for the light source. Iemploy in the lamp housing of my invention, a mounting for the lightsource 00 constructed in accordance with my Patent, No. 1,735,334, Nov.12, 1929. The assembly of the control equipment and the construction ofthe lamp housing is such that a minimum space is required for theinstallation of the lamp housing. In installing the lamp housing onpicture projecting machines, the housing may be vertically positionedwith respect' to the projecting machine and readily accessible to theoperator.

Referring to the drawings in more detail,

reference character 1 designates a vertical wall structure on which theparts of the control equipment and the light source are mounted.Reference character 2 designates a wall member projecting at rightangles from rear Wall 1. The condensing lens system for the soundpicture projection apparatus is represented at 3 within tubular member 4which is arranged adjacent a light aperture 39 in the M1112. The lamphousing has bottom member 5 forming a lower closure for the housing. Theadjustable lamp holder is mounted from a bracket 6 on rear wall 1 andincludes the supporting block 7 and socket 35 member 8 for receiving thelamp 9. The various adjustments which are permitted for the lamp sourcehave been clearly set forth in my patent to which reference is made fora more detailed disclosure of the light source. The controls for thelight source are mounted upon the-swinging panel structure representedat 10 and 11 as pivotally mounted at 19 to the rear wall 1. The panel 11provides a support for the ammeter 12, the variable control rheostat 13and switch member 15. The rheostat 13 is controlled from the front ofthe panel by means of control knob 14. Switch member 15 may be snappedon. or off from the front of the panel 11 by means of control knob 16.The panel is moved outwardly or returned to closed position by means ofknob 17 which may control the latch 18 which engages the wall 2 forsecuring the panel 11 in closed position with respect to the Wall member2. By reason of the fact that both the front panel 11 and side wallpanel 10 may be substantially removed from the light source mounting,suflicient working space is obtained for effecting the requiredadjustments within the lamp housing. The leads from a series circuit areshown including ammeter 12, control rheostat 13, switch 15 and theterminals of the light source 9 extend outside of the lamp housing to asuitable power source. Sufficient flexibility and slack may remain inthe leads to allow the free movement of the swinging panel from aposition entirely enclosing the light source 9 to a position remote fromthe light source 9. The alignment of the light source 9 with thecondensing lens system and light slit inithe sound picture pro ectingsystem, may be readily secured by adjustment of the block 7 with respectto the supporting bracket 6.

The construction of lamp housing and control panel of my invention hasbeen found to be extremely practical in picture projecting systems andwhile I have described a preferred embodiment of the invention, I desirethat it be understood that modifications may be made and that nolimitations are intended other than are imposed by the scope of theappended claims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is as follows:

1. A lamp housing for talking picture projecting machines comprising abox like structure having a plurality of side walls two of which areintegrally connected and hingedly attached to a third side permittingtwo complete sides of said structure to be swingingly moved togetherwith respect to the other sides for easy access to the inside of thehousing, an adjustable support for a light source, a lens system at oneside of said lamp housing to which said light source is aligned andelectrical instruments carried by one of the integrally connected sidewalls of said box like structure for governing and observing theoperation of said light source.

2. A lamp housing for talking picture projecting machines comprising abox like structure having four side walls, top and bottom Walls, two ofsaid side walls being fastened together and swingingly mounted on athird side wall to permit easy access to the inside of said housing, anadjustable light source mounted on said third side wall, a lens systemaligned with said light source and mounted on the fourth side wall, andinstruments mounted on one of the said swingingly mounted side walls forgoverning and observing the operation of said light source.

3. A lamp housing for talking picture projecting machines comprising a,pair of wall portions disposed substantially at right angles to eachother, each of said Wall portions consisting of two side walls, anadjustable light source supported from one of said wall portions, a lenssystem positioned in allgnment'with said light source and carried by theother of said wall portions and a right angularly disposed wall portionpivotally mount ed with respect to said first mentioned wall portion,permitting two of the side walls of said housing to be moved togetherwith respect to the other two side walls for easy access to the interiorof said housing, said right angularly disposed wall portion carryingcontrol equipment on the interior wall thereof for governing theoperation of said light source.

In testimony whereof I aflix my signature.
